The Dometic DM2872RB1 is a different size and shape than your N811F, so compare the DM2872's cutout dimensions (height, width and depth) to your opening before you order. The Polar N8XF is the usual replacement for the N811. Send us your cutout measurements and we'll help you choose. Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you.
